7.1 Variable measuring area
For small parts and wires
≥ ∅
0,3 mm
While the deplating area with the rubber gasket or a
mask is always clearly defined by the size of the gas-
ket, the electrolyte-cup-procedure requires a calcula-
tion to be made in order to determine the de-plating
area. GalvanoTest 3000 allows de-plating areas to be
adjusted from 0,25...16 mm

-
Choose the appropriate solution according to the
electrolyte selection table (section 4.2.3) and fill
the cup to about up to 1 cm from the rim.
-
Areas of samples which are not be measured or
the ends of wires have to be insulated by lacquer,
for instance.
Note:
Use the black and yellow connecting cable for meas-
urements with the cup!
-
Adjust measuring area to „K“. Use the wire hol-
der (46) instead of the rubber gasket holder (42c)
(see. Fig. 4). Make further adjustments according
to section 4.
-
Dip the sample into the electrolyte cup ensuring
that the area dipped into the cup approximately
corresponds to your setting of measuring area.
-
Ajust the electrolyte cup holder so that the sample
is in the middle of the cup. The sample must not
touch the cup at any point, even on the bottom.
-
Fit the cathode plug into the socket on the cup
and fix the sample clamp to the sample. The
contact point must be clean so that a good
electrical contact is made.
-
The solution can be used for several
measurements (20 to 30 depending on the size
of the samples), but is should not be left in the
cup for a longer time, but removed and stored in
a suitable bottle. Do not refill into the bottle with
new solution!
-
Press START/STOP-key. The following message
is shown on the alphanumerical display:
„Measuring area?“. Use ARROW-keys for setting
the approximate measuring area.
